The only programmers that are better that C programmers are those who code in 1's and 0's

The other problem is how can I convert string to char*

string foo = "Hello World";

fixed (char* fp = foo)
{
  var i = crc16(fp, (ushort) foo.Length, 0);
}

Would you say that the Crc method look good after my C# interpretation?

static unsafe ushort crc16(char* pBuf, int Len, ushort InitialCrc)
{
  ushort crc = InitialCrc; //?

  for (int i = 0; i < Len; i++)
  {
    crc = (ushort)((crc >> 8) | (crc << 8));
    crc = (ushort)(crc ^ *pBuf);
    crc = (ushort)(crc ^ ((crc & 0xff) >> 4));
    crc = (ushort)(crc ^ (crc << 12));
    crc = (ushort)(crc ^ ((crc & 0xff) << 5));
    pBuf++;

  return crc;
